APPARATUS FOR FIL'IERNG AND BOTILING FLUIQDS UNDER PRESSURE.

Application led January 20, 1928.

The invention relates to apparatus for bottling fluids under pressureand especially effervescent fluids, which are to be filtered at the sametime they are bottled.

The present invention is an improvement on my invention covered in thecopending application Serial No. 236,309 filed Nov. 28, 1927.

The object of the present invention is to provide a bottling andfiltering device the different compartments whereof are all formed byone integral container.

Other objects of the invention not specifically mentioned may he easilyascertained and understood fromv the followingdoser-ip tion in.connection with the accompanying drawings forming a part thereof. It ishowever to be noted, that the invention is not to be limited orrestricted to the exact construction or formation shown in the drawingsand described in the specification, but that the invention is only to belimited by the scope of the claims appended hereto.

In the drawings:

Fig. 1 is an elevation of the apparatus according to the presentinvention, and

Fig. 2 is a vertical section through said apparatus.

The body of the device consists of a con tainer 5 preferably made fromsheet copper. At the top said container is provided with a flange 6.This flange is created by bending the metal, of which the container' ismade, outwardly at right angles to the walls of said container, and thenbending the metal forming the flange back upon itself, so that thefiange consists of two layers of nieta.. In order to reinforce theflange still more a steel ring 7 may be clamped in between the twolayers of metal mentioned above.

To close the container 5 a lid 8 is pro-- vided. This lid has a flange9, whioh is made in the sameway as the 6. @n

the latter a plurality of clamps 10 arc hingedly fastened, which can beswung` into clamping position as shown in the drawings to engage theflange of the lid and force the same down onto the container. A rubberring 11 or any other suitable packingring may be arranged between thetwo flanges, so that the lid will close the container hermetically, whenthe clamps are forced down onto the flange 9 of the lid.

rihe container may be provided with a plurality of legs 12. In adistance of about one third of the height of the container from SerialNo. 248,077.

the bottom a supporting ring 1B or the like is -fastened to the innerface of the container, and a comparatively strong` false bottom plate11i rests on said ring. A spacer ring 15 is placed on top of said plateand a coarse sieve plate 1G is supported by said spacer ring. On top ofthis sieve plate a line sieve plate 17 is located, and this platecarries a layer of filter material 18, for infx stance cotton. Anotherline sieve plate 19 rests on said filter material. and al second coarsesieve plate 2O is arranged on top of the last named plate. A secondspacer ring 21 rests on top of the plate 2O and abuts with ils upper rimthe lid 8. l/Vhen the filter material is arranged in its place it isloosely packed, so that the upper rim of the ring 21. extends somewhatbeyond the container. lhen then the lid is forced down, the filtermaterial is compressed, and the plate 14C is forced upon the supportingring 13. ln order to make the connection between the plate and the ringleak-proof a packing ring 22 or the like may be arranged be tween thetwo members. A short inlet pipe 23 provided with a valve 24 leads intothe interior of the container adjacent the upper rim thereof, and abaffle plate 25 is fastened to the inner face of the container in such amanner, that any liquid entering` the container through the inlet pipewill be deflected against the wall of the container and will flow downon said wall instead of falling freely onto the filter. in this mannerobjectionable foaming` of the liquid to be treated is obviated. Thespacer ring 21 has a cut-out portion, as indicated in llig. 2 to permitof the mounting of the baffle plate 25 and the entrance of the fluid tobe treated.

From the space between the plate 14 and the sieve plate 16 a pipe 26leads to the space below the plate 14, and in this pipe a valve 27 isarranged. A slot or opening is provided in the spacer ring` 15 to permitthe pipe to communicate with the interior of the container. Adjacent theplace where the pipe 26 enters the space below the plate 111, a secondbaffle plate 28 is fastened to the inner face of the wall of thecontainer for the same purpose as described above with reference to thebaffle plate 25.

lnto the wall of the container two fluid gauges 29 and 3() are set, theone above the level of the upper coarse sieve plate 20, when the lid ispressed down onto the container, and the other one below the level ofthe ion `plate I4. Amanometer 8l may be arranged on the lid 8. y

A tank 32 is fastened in anyfconvenient manner to the outside ot thecont-ainer, and adjacent said tank an air pump 33 is also mounted onsaid container. A tube 34 leads from the pump to the` tank, so that comfpressed air may be stored in said tank. A pipe 35 leads form the tankinto the upper part of the container and a stop cock 8bV regulates theflow of compressed air through said nipple. Adjacent the bottom 'of thecontainer a cock 4l is arranged for draining the fluid from the lowerportion of the container.

valve 42 is provided.

The device is operated ,in the following manor: The liquid to be treatedis brought into the upper portion of the container in any convenientmanner. Vhen for instance the liquid to be treated is in a can, the lid8 may be removed and the liquid may then be poured into the container,whereupon the lid is fastened tightly onto the container by means of theclamps l0. Or, if the liquid to be treated should be contained in ademijohn or the like a tube extending through the cork of the demijohnmay be immerged into the fluid to be treated and the other end of p thetube .may then be attached to the inlet pipe 23. Another tube may befastened to the nipple 39 and may lead through thel cork of thedemijohn. The valve 24 and the cock A are opened, after the lid 8 hasbeen seated In order to let the superfluous air out of the lower portionof the container av plates and the filter material. The valve 27 isopened and the filtered liquid will flow into the lower portion oi' thecontainer. If the liquid being treated is an effervescent liquid, suchas ginger aleor the like,`vit is vnecessary to keep the liquidcontinuously under pressure, and for that purpose the cock 38 in pipe 87is opened permitting coinpressed air to flow into the part of thecontainer underneath the false bottom plate 14. By opening the cock orspigot 4l the filtered liquid may be drawn from the con*- tainer, whilethe liquid is under pressure. What I claim as newis: Y l. In a device ofthe class described a container, a lid therefor, means forY seating saidlid tightly and firmly onto the container,

a false bottom in said container arranged at a distance from the realbottom thereof, a filter arranged in said container ata distance abovesaidl false bottom, an air compressing derice communicating with the topportion of the container, an inlet'pipe communicating with said portion,a pipe connecting the space between the filter and the false bottom.with the space beneath said false" plate on top of said filtermaterial, va secon-dy spacer ring seated on said u'ppersieve plate, thelid being adapted to engage the upper rim of said ring and to force itdownwardly, when the lid is being clamped tightly onto the container,an'inlet communicating with the top portion oi the container, an aircompressing means communicating with the same portion, a pipe connectingthe space between the filter and the false bottom with the spaceunderneath saidv false bottom, means for conducting compressed air intosaid last named space, and an outlet on the container adjacent thebottom thereof.

In witness Awhereof I affix my signature.V
